Melalui susunan roda gigi bevel internal (set roda gigi tahap reduksi 3-4), kecepatan input ini diubah dengan rasio 1:1,9, menghasilkan kecepatan putar output yang sesuai sekitar 284 r\/min untuk menggerakkan cakram pemutar, pengaduk, atau auger penyebar pupuk. Secara bersamaan, gearbox melipatgandakan torsi dari poros input hingga maksimum 99 N\u00b7m pada poros output, memastikan mekanisme pemutaran menghasilkan gaya sentrifugal yang cukup untuk menyebarkan pupuk granular atau cair secara merata di seluruh lebar penyebaran yang diinginkan. Konversi kecepatan-ke-torsi yang tepat inilah yang membedakan gearbox pertanian berkualitas tinggi dari pengganti generik, yang secara langsung memengaruhi keseragaman dan akurasi distribusi pupuk.<\/p>\n<p>Rumah aluminium yang ringan namun kuat (berat unit total 4,1 kg) membungkus roda gigi bevel yang digiling presisi dan poros baja yang dikeraskan yang berputar di bantalan elemen gelinding berkualitas. Segel oli multi-bibir yang dipasang di kedua ujung poros input dan output mencegah masuknya debu pupuk, kelembapan, sisa tanaman, dan partikel tanah yang jika tidak akan menyebabkan keausan abrasif yang dipercepat pada sisi roda gigi dan jalur bantalan. Bak oli tertutup, diisi dengan 0,35 L pelumas roda gigi SAE 80W-90, menciptakan lapisan hidrodinamik antara semua permukaan roda gigi dan bantalan yang bergerak, secara drastis mengurangi kontak logam-ke-logam dan pembangkitan panas selama operasi lapangan terus menerus. Ketahanan korosi alami rumah aluminium sangat berharga mengingat lingkungan kimia yang sangat agresif yang diciptakan oleh pupuk nitrogen, fosfat, dan kalium yang ditemui dalam operasi penyebar pupuk pada umumnya.<\/p>\n<p>The L-25A gearbox is rated to handle a maximum continuous input power of 11 kW (15 HP). The internal gear and shaft assembly is designed with calculated safety margins to absorb the momentary shock loads and torque spikes that are unavoidable during the start-up of a loaded spreader disc, changes in spreading rate, or brief material bridging in the hopper outlet. When the gearbox is paired with a properly rated PTO drive shaft incorporating a slip clutch or shear bolt overload protection device, the system is further protected against catastrophic torque events caused by foreign object ingestion or sudden disc blockages. This layered approach to load management ensures both the fertilizer spreader gearbox and the upstream driveline components are protected from damage during real-world agricultural use.<\/p>\n<p>To maintain optimal internal conditions, the gearbox is supplied dry and must be filled with SAE 80W-90 gear oil to the specified 0.35 L capacity before first operation. The initial oil change should be performed after 50 to 70 operating hours, as this early service interval removes metal particles generated during the gear and bearing bedding-in period. Thereafter, oil changes at 500-hour intervals or annually prevent oxidation and contamination of the lubricant, which would otherwise lead to inadequate film strength, elevated operating temperatures, and premature internal wear. Checking the fertilizer spreader gearbox oil level at the start of each season and after extended storage periods is strongly recommended as part of a responsible preventive maintenance regime.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8052 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2.webp\" alt=\"Gearbox Penyebar Pupuk\" width=\"1200\" height=\"820\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2-980x670.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-2-480x328.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Bidang Aplikasi<\/h2>\n<div>\n<h3>Pertanian Tanaman<\/h3>\n<p>Essential for the uniform application of granular and liquid fertilizers across arable crops including grains, cereals, vegetables, and fruits. The 1:1.9 gear ratio ensures the spinner discs achieve the correct speed for wide, even spread patterns, promoting optimal nutrient absorption at the root zone, preventing localized burning, and maximizing yield potential per hectare.<\/p>\n<\/div>\n<div>\n<h3>Pengelolaan Padang Rumput<\/h3>\n<p>In livestock farming operations, this\u00a0fertilizer gearbox\u00a0ensures even distribution of nitrogen and compound fertilizers across permanent pastures and temporary leys, promoting vigorous grass growth and improving forage quality.

Dibuat dengan toleransi dimensi yang ketat dan dilengkapi dengan alur pasak atau spline sesuai spesifikasi varian model, poros keluaran ditopang oleh bantalan elemen gelinding yang kokoh di kedua ujungnya untuk mengelola beban radial dan aksial yang dihasilkan oleh berat dan ketidakseimbangan sentrifugal dari rakitan cakram pemutar selama operasi kecepatan tinggi di lapangan.<\/p>\n<p>Bantalan<br \/>\nDeep groove ball bearings or tapered roller bearings, selected according to the load requirements of each shaft position, support both the input and output shafts within the housing bores. These standard-dimension bearings from recognized manufacturers are dimensioned to handle the combined radial and axial loads generated during spreader disc operation, and their dimensions are fully interchangeable with original Comer L-25A specification bearings, simplifying sourcing of fertilizer spreader gearbox parts during overhaul.<\/p>\n<p>Segel Oli<br \/>\nRotary shaft lip seals are installed at every point where a rotating shaft exits the aluminium housing, creating a positive barrier against the ingress of fertilizer dust, moisture, crop material, and soil contamination that would otherwise rapidly destroy the gear oil film and accelerate internal wear. Manufactured from NBR or FKM rubber compounds selected for compatibility with 80W-90 gear oil and agricultural chemical environments, these seals maintain their sealing integrity across the full operating temperature range of the gearbox.<\/p>\n<p>Sistem Pelumasan<br \/>\nThe L-25A employs a splash lubrication system in which the rotating bevel gear picks up SAE 80W-90 oil from the 0.35 L reservoir at the base of the housing and distributes it to all gear tooth contact zones and bearing positions as it rotates. An oil level check plug and drain plug are provided in accessible positions on the housing. This self-contained oil-bath system requires no external pump or filtration equipment, making the fertilizer gearbox self-sufficient and simple to maintain in the field environment.<\/p>\n<p>Mounting Hardware and Fasteners<br \/>\nRumah gearbox ini memiliki empat lubang pemasangan berulir atau berlubang pada pola lingkaran baut yang sesuai dengan spesifikasi asli Comer L-25A, dan dapat menggunakan pengencang metrik standar. Dimensi flensa pemasangan (lingkaran baut 74 mm x 74 mm dengan lubang berdiameter 11 mm seperti yang ditunjukkan pada gambar dimensi) memungkinkan pemasangan langsung dengan baut ke rangka pemasangan gearbox pusat penyebar pupuk tanpa modifikasi. Pengencang baja tarik tinggi yang digunakan untuk mengamankan gearbox ke rangka penyebar merupakan komponen keselamatan yang sangat penting dan harus dikencangkan sesuai dengan nilai yang ditentukan oleh pabrikan.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8073 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp\" alt=\"Gearbox Penyebar Pupuk\" width=\"1000\" height=\"1000\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-5-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" \/><\/p>\n<h2>How to Correctly Install the L-25A Gearbox<\/h2>\n<p>1. Inspeksi Pra-Pemasangan<br \/>\nSebelum memasang gearbox, periksa semua permukaan yang bersentuhan pada rangka penyebar dan rumah gearbox untuk memastikan tidak ada gerigi, cat yang menetes, kotoran, atau korosi yang dapat mencegah kontak langsung antar permukaan. Pastikan pola lubang baut pada rangka penyebar sesuai dengan pola pemasangan L-25A 74 mm x 74 mm dengan lubang celah 11 mm. Periksa ujung poros input dan output untuk memastikan tidak ada kerusakan akibat pengiriman pada gigi spline atau alur pasak. Jangan memasang unit yang rusak.<\/p>\n<p>2. Initial Oil Fill Before Mounting<br \/>\nThis gearbox is supplied dry without oil. Before installation, fill the gearbox with 0.35 L of SAE 80W-90 gear oil through the designated fill port, then refit and tighten the fill plug securely. Checking the <a href=\"https:\/\/korea-transmission.com\/id\/fertilizer-spreader-gearbox\/\"><strong>fertilizer spreader gearbox<\/strong><\/a> oil level with the unit in its operating attitude ensures the correct fill volume is confirmed before any shaft rotation occurs. Never operate the gearbox without oil as this will cause immediate and irreversible internal damage.<\/p>\n<p>3. Secure Mounting to Spreader Frame<br \/>\nPasang kotak roda gigi ke rangka pemasangan kotak roda gigi pusat alat penyebar dan sejajarkan keempat lubang pemasangan. Masukkan baut M10 kelas 8.8 atau lebih baik, ring polos, dan ring pegas. Kencangkan keempat pengencang dengan tangan sebelum mengencangkan secara diagonal dalam dua tahap hingga nilai torsi yang direkomendasikan (biasanya 40-45 N\u00b7m untuk baut M10 kelas 8.8). Pengencangan diagonal mencegah distorsi rumah dan memastikan flensa pemasangan ditarik secara seragam tegak lurus ke permukaan rangka, menjaga keselarasan roda gigi internal yang benar.<\/p>\n<p>4. Connect the PTO Drive Shaft<br \/>\nGeser poros penggerak PTO dengan sambungan enam alur 1-3\/8\u2033 ke poros input gearbox, pastikan alur terpasang sepenuhnya hingga cincin pengunci atau penahan pin pengunci berbunyi klik dan mengamankan sambungan secara aksial. Pastikan kopling overrun atau kopling selip poros PTO diorientasikan ke arah yang benar seperti yang ditandai oleh pabrikan. Verifikasi bahwa panjang poros PTO memungkinkan sudut operasi yang benar dan bahwa tumpang tindih yang memadai dari bagian poros teleskopik dipertahankan di seluruh rentang geometri traktor-ke-penyebar.<\/p>\n<p>5. Attach the Spreader Disc Assembly<br \/>\nFit the fertilizer spreader disc hub onto the 25 mm output shaft, engaging the key or spline drive as appropriate to the specific model. Retain the disc hub using the specified locking method, whether a shaft end nut with cotter pin, a roll pin, or a flanged hub bolt pattern. Check that the disc runs true without visible radial run-out or wobble, as disc imbalance at 284 r\/min output speed will generate vibration loads transmitted back into the gearbox output shaft bearings, shortening their service life.<\/p>\n<p>6. Check PTO Shaft Guard and Safety Chain<br \/>\nPasang pelindung luar plastik poros PTO di atas poros penggerak dan hubungkan kedua ujung rantai pengaman ke titik jangkar tetap pada traktor dan alat penyebar masing-masing sehingga pelindung tidak dapat berputar bersama poros. Pelindung harus menutupi area dudukan poros input gearbox tanpa menyentuh rumah gearbox. Ini adalah persyaratan keselamatan wajib: poros PTO yang berputar tanpa pelindung merupakan bahaya tersangkut yang sangat besar, dan banyak yurisdiksi memberlakukan kewajiban hukum kepada operator untuk memastikan pengamanan yang benar sebelum pengoperasian di lapangan.<\/p>\n<p>7. No-Load Run-In and Final Checks<br \/>\nWith all personnel clear of the spreader and PTO arc, engage the PTO at low engine RPM and run the gearbox for 5 minutes without load, listening for any abnormal noise such as grinding, knocking, or rattling that would indicate incorrect assembly or internal contact. Stop the PTO, allow 2 minutes to elapse, then check for any oil leaks at the shaft seals or housing joint faces. Recheck all mounting fastener torques after this initial run-in. Only after confirming all checks are satisfactory should the spreader be loaded and taken into field operation for the first time. Contact your CMN Transmission dealer for technical support if any issues are observed during the run-in period.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8093 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp\" alt=\"Aplikasi Gearbox Penyebar Pupuk\" width=\"1200\" height=\"900\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-980x735.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/0_Fertilizer-Spreader-Gearbox-Applications-2-480x360.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Correct Maintenance of the L-25A Gearbox<\/h2>\n<div>\n<h3>Break-In Oil Change (50-70 Hours)<\/h3>\n<p>Drain and replace the gear oil after the first 50 to 70 operating hours regardless of its apparent visual condition. This critical service removes fine metallic particles shed by the gear flanks and bearing surfaces during the initial bedding-in period. If left in the gearbox, these particles act as an abrasive lapping compound that accelerates wear. Drain the old oil while it is still warm from operation to ensure complete removal of suspended particles, then refill with fresh SAE 80W-90 to the correct level.<\/p>\n<\/div>\n<div>\n<h3>Regular Oil Level Monitoring<\/h3>\n<p>Check the\u00a0fertilizer spreader gearbox oil level\u00a0at the start of each operating season, after any prolonged storage, and every 50 hours of in-season operation. With the spreader on level ground, remove the oil level check plug and verify oil is present at the port. A low level indicates either seal wear with external leakage or emulsification from moisture ingress. Top up with the correct SAE 80W-90 grade only. Never mix different viscosity grades or oil types as this can compromise lubricant film strength.<\/p>\n<\/div>\n<div>\n<h3>Scheduled Oil Changes (500 Hours \/ Annual)<\/h3>\n<p>Perform a full drain and refill of the 0.35 L SAE 80W-90 oil charge every 500 operating hours or at least once per year, whichever falls first. Oxidized gear oil loses its extreme-pressure additive package, reducing protection of heavily loaded gear tooth contact zones. When draining, check the drained oil for metallic debris, milky emulsification (indicating moisture ingress), or unusual discoloration. Any of these signs warrant a more thorough inspection of the gearbox interior, oil seals, and housing integrity before returning to service.<\/p>\n<\/div>\n<div>\n<h3>Oil Seal and Gasket Inspection<\/h3>\n<p>Inspect both input and output shaft oil seals visually at each service interval and after any prolonged storage, checking for cracking, hardening, or distortion of the rubber lip, and for oil weeping at the seal-to-shaft interface. The housing joint gasket should also be checked for compression set or cracking. Seals showing any sign of deterioration must be replaced immediately, as fertilizer chemicals rapidly attack compromised seals and contaminate the gear oil once an ingress path is established. Replacement seals matching original dimensions are available as\u00a0fertilizer spreader gearbox parts.<\/p>\n<\/div>\n<div>\n<h3>Mounting Fastener Torque Verification<\/h3>\n<p>Vibration and thermal cycling during field operation can cause mounting fasteners to gradually loosen, potentially allowing the gearbox to shift position relative to the spreader frame. Check and re-torque all four mounting bolts to their specified torque values at the start of each season and after every 100 hours of operation. Pay particular attention to the PTO drive shaft yoke retaining hardware and the spreader disc hub locking fastener. Loose mounting allows the gearbox to rock under load, generating fretting corrosion at the mounting face and abnormal loads on the gear mesh.<\/p>\n<\/div>\n<div>\n<h3>End-of-Season Storage Preparation<\/h3>\n<p>At the end of the spreading season, clean the gearbox exterior thoroughly with water to remove all traces of fertilizer residue, which is hygroscopic and corrosive. Apply a coat of light anti-corrosion oil spray to all exposed metal surfaces, shaft ends, and the housing exterior. Change the gear oil before storage rather than at the start of the next season, as used oil becomes acidic over storage periods and will attack internal surfaces. Store the spreader under cover in a dry location to protect the gearbox and associated hardware from moisture-induced corrosion during the off-season period.<\/p>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8002 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1.35-1.webp\" alt=\"Gearbox Penyebar Pupuk L-25A 1.35-1\" width=\"800\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1.35-1.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/L-25A-Fertilizer-Spreader-Gearbox-1.35-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" \/><\/p>\n<h2>Fertilizer Spreader Gearbox and PTO Driveline Shaft<\/h2>\n<p>Poros Power Take-Off (PTO) adalah penghubung mekanis antara traktor dan alat-alat yang terpasang. Distandarisasi oleh ISO 500 pada 540 r\/min untuk aplikasi pertanian, poros PTO mentransmisikan daya mesin dari poros PTO yang digerakkan oleh gearbox traktor ke poros input alat melalui poros penggerak teleskopik yang dilengkapi dengan sambungan universal di kedua ujungnya. Tanpa PTO, alat-alat yang dipasang pada traktor seperti penyebar pupuk, mesin pemotong rumput, mesin pengemas jerami bundar, dan mesin pengolah tanah putar tidak dapat berfungsi. Oleh karena itu, poros PTO bukan hanya fitur kenyamanan tetapi juga pasokan daya fundamental untuk seluruh keluarga mesin pertanian yang digerakkan PTO yang banyak digunakan di seluruh dunia.<\/p>\n<p>Fertilizer spreader gearboxes serve as the critical power transformation device between the raw PTO output and the application mechanism of the spreader. The tractor PTO delivers 540 r\/min at relatively low torque. The fertilizer distributor gearbox accepts this input and converts it to the speed and torque required by the spinning disc or auger mechanism. In the case of the L-25A at a 1:1.9 ratio, the input speed of 540 r\/min is stepped up to approximately 1,026 r\/min at the output, while the corresponding output torque is delivered at up to 99 N\u00b7m to drive the disc at the rotational speed needed for correct fertilizer throw distance and spread pattern. Different fertilizer spreader gearbox ratio values are available across the Comer L-25A family to suit different spreader designs, disc diameters, and target spread widths, allowing the machine designer to optimize spreading performance for their specific product.<\/p>\n<p>Poros input gearbox L-25A menerima fitting yoke enam-spline standar 1-3\/8\u2033 yang digunakan pada sebagian besar poros penggerak PTO pertanian 540 r\/min di Eropa. Saat memilih atau menentukan poros penggerak PTO untuk dipasangkan dengan gearbox ini untuk aplikasi penyebar pupuk, beberapa parameter harus dikonfirmasi: poros harus mampu mentransmisikan setidaknya 11 kW pada 540 r\/min secara terus menerus; panjang terlipat dan diperpanjang harus memberikan pengikatan dan jarak bebas yang tepat di seluruh rentang posisi pengangkatan traktor; sudut sambungan universal harus tetap berada dalam batas yang direkomendasikan pabrikan untuk menghindari resonansi yang disebabkan oleh getaran; dan poros harus menggabungkan perangkat perlindungan beban berlebih yang sesuai, baik kopling selip atau kopling baut geser, untuk melindungi gearbox dan poros penggerak traktor jika terjadi penyumbatan cakram atau benturan benda asing.<\/p>\n<p>Saat PTO traktor diaktifkan, daya putar mengalir dari poros PTO traktor, melalui poros penggerak PTO teleskopik, ke poros input gearbox L-25A melalui sambungan beralur 1-3\/8\u2033. Set roda gigi bevel mengubah daya ini dengan rasio 1:1,9 sebelum mengirimkannya ke poros output, yang menggerakkan cakram penyebar. Operator mengontrol laju penyebaran melalui pengaktifan PTO traktor dan pembukaan pelat penutup penyebar, sementara gearbox secara konsisten mempertahankan kecepatan cakram yang tepat terlepas dari variasi kecil pada throttle. Dengan demikian, gearbox pertanian untuk penggunaan penyebar pupuk bertindak sebagai konverter daya dan elemen penyangga dalam sistem penggerak, menyerap variasi kecepatan kecil sebelum dapat memengaruhi keseragaman pola penyebaran di seluruh lahan.<\/p>\n<p>A worn or incorrectly specified interface between the PTO shaft and the fertilizer spreader gearbox introduces speed variation at the disc, directly translating into uneven fertilizer distribution. Excessive play in the spline connection causes rotational shock loading each time the disc encounters resistance, accelerating wear of both the gearbox input shaft splines and the PTO shaft yoke. Choosing a high-quality, correctly specified agricultural gearbox from a reputable fertilizer spreader gearbox manufacturer such as CMN Transmission, and pairing it with a properly matched PTO drive shaft, is the foundation of accurate, efficient, and economical fertilizer application in every field condition encountered during the growing season.<\/p>\n<table>\n<tbody>\n<tr>\n<td><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8021 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 800px, 100vw\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91.webp 800w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/09\/T-281A-Fertilizer-Spreader-Gearbox-1-2.91-480x480.webp 480w\" alt=\"Gearbox Penyebar Pupuk T-281A 1-2.91\" width=\"800\" height=\"800\" \/><\/td>\n<td><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-343 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2025\/04\/PTO-Shaft-480x480.webp 480w\" alt=\"Poros PTO\" width=\"1000\" height=\"1000\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Mengapa Memilih Gearbox Penyebar Pupuk dari CMN Transmission?<\/h2>\n<p>Korea CMN Transmission Co., Ltd. didirikan pada tahun 2000 dan berkantor pusat di Sandan-o, Danwon-gu, Ansan-si, Gyeonggi-do, Korea.

CMN L-25A dirancang sebagai pengganti langsung (drop-in) yang sesuai dimensi dan fungsinya untuk unit Comer L-25A asli. Semua dimensi penting cocok, termasuk lingkaran baut pemasangan (74 mm x 74 mm, 4 lubang M10), poros input enam alur 1-3\/8\u2033, dan diameter poros output 25 mm. Tidak diperlukan pengerjaan mesin, adaptor khusus, atau modifikasi braket untuk pemasangan pada mesin apa pun yang awalnya menggunakan gearbox Comer L-25A dengan rasio 1:1,9.<\/p>\n<p><strong>Q: What oil should I use to fill the L-25A fertilizer spreader gearbox, and what is the correct oil capacity?<\/strong><br \/>\nA: Use SAE 80W-90 GL-4 or GL-5 gear oil. The L-25A has a maximum oil capacity of 0.35 litres. The gearbox is supplied without oil and must be filled before first operation. Perform the first oil change after 50 to 70 operating hours to flush out bedding-in wear particles, then change the oil every 500 hours or annually. Correct fertilizer spreader gearbox oil level should be confirmed with the unit in its operating attitude before starting the machine.<\/p>\n<p><strong>Q: What does the 1:1.9 fertilizer spreader gearbox ratio mean, and does CMN offer other ratios?<\/strong><br \/>\nA: A 1:1.9 fertilizer spreader gearbox ratio means that for every one revolution of the input shaft, the output shaft completes 1.9 revolutions. At a standard 540 r\/min PTO speed, this delivers approximately 1,026 r\/min at the output to drive the spreader disc. This ratio is commonly specified for standard twin-disc fertilizer spreader designs. The Comer L-25A series includes models with ratios ranging from 1.25 to 3.00 to suit different spreader disc diameters and target throw widths. Contact CMN Transmission for availability of other ratio variants.<\/p>\n<p><strong>Q: What is the maximum input power and torque this agricultural gearbox can handle continuously?<\/strong><br \/>\nA: The L-25A agricultural gearbox is rated for a maximum continuous input power of 11 kW (15 HP) at 540 r\/min, with a corresponding maximum output torque of 99 N\u00b7m. These ratings represent the continuous duty capacity under normal operating conditions with correct oil fill and adequate ambient temperature. Brief overload peaks above the rated power, such as those occurring during disc start-up, are managed by the gear safety factor built into the design, but the gearbox should always be paired with an appropriate PTO overload protection device.<\/p>\n<p><strong>Q: Can the L-25A fertilizer gearbox be used on spreaders applying liquid fertilizer, lime, or compost?<\/strong><br \/>\nA: Ya. Rumah aluminium tertutup dan segel oli multi-bibir pada L-25A memberikan perlindungan efektif terhadap bahan korosif dan abrasif yang ditemui saat menyebarkan pupuk granular, kapur pertanian, kapur giling, dolomit, dan kompos granular. Untuk aplikasi pupuk cair, pastikan sambungan poros keluaran dan hub cakram sesuai untuk lingkungan basah dan pelindung percikan yang memadai terpasang untuk mencegah semprotan pupuk cair mencapai sambungan rumah gearbox dan segel oli selama periode pengoperasian yang lama.<\/p>\n<p><strong>Q: What is the weight of the L-25A gearbox and why does the housing material matter?<\/strong><br \/>\nA: L-25A memiliki berat 4,1 kg, berkat rangka aluminium cornya. Bobot yang rendah ini mengurangi beban momen tambahan yang ditempatkan pada rangka tengah dan sambungan pengait alat penyebar pupuk, yang penting untuk model alat penyebar yang kompak dan lebih ringan. Ketahanan korosi bawaan aluminium merupakan keuntungan signifikan dalam lingkungan pupuk kimia, di mana rangka besi cor dengan kekuatan yang setara akan memerlukan perlindungan permukaan yang cermat dan berkelanjutan untuk mencegah karat pada dinding rangka dan kontaminasi oli roda gigi dengan partikel oksida besi.<\/p>\n<p><strong>Q: Do you hold the L-25A fertilizer spreader gearbox in stock for immediate dispatch?<\/strong><br \/>\nA: CMN Transmission maintains substantial finished goods stock of the L-25A and other high-demand fertilizer spreader gearboxes to support urgent replacement orders during the peak spreading season. Contact our sales team with your order quantity and destination for a current lead time and shipping cost quotation. For dealers and importers requiring regular stocking quantities, we recommend establishing a blanket order arrangement to ensure priority allocation of stock during seasonal demand peaks when the L-25A fertilizer spreader gearbox for sale inquiry volume is highest.<\/p>\n<p><strong>Q: How do I identify which specific L-25A variant matches my existing Comer gearbox configuration?<\/strong><br \/>\nA: Seri Comer L-25A mencakup berbagai varian kode, seperti yang ditunjukkan dalam tabel referensi katalog gearbox Comer (nomor kode dalam rentang 9.124.xxx). Parameter kunci yang perlu diidentifikasi adalah: rasio gigi (cari \u201c1.90\u201d di kolom rasio), jenis koneksi poros input (tipe poros X, Y, atau Z), dan tipe poros output. Gambar spesifikasi referensi di atas menunjukkan kode tipe poros dan konfigurasi pemasangan. Berikan tim teknis kami nomor kode Comer Anda yang sudah ada (misalnya, 9.124.912 atau 9.124.019) dan kami akan mengkonfirmasi padanan CMN yang tepat dan memeriksa ketersediaan stok.<\/p>\n<p><strong>Q: What is the expected service life of the L-25A fertilizer spreader gearbox under normal agricultural use?<\/strong><br \/>\nA: Under correct installation conditions, with proper initial and periodic oil changes using SAE 80W-90, and within the rated power and speed limits, the L-25A is designed for a service life exceeding 1,000 operating hours. Many units in the field significantly exceed this figure when regularly maintained. The primary wear items are oil seals and bearings, both of which are individually replaceable as standard fertilizer spreader gearbox parts, meaning the aluminium housing and gear set can often be rebuilt rather than replaced, extending the total useful life of the unit considerably beyond the initial 1,000-hour design target.<\/p>\n<p><strong>Q: Can CMN Transmission supply L-25A gearboxes with custom shaft configurations or special mounting options?<\/strong><br \/>\nA: Yes. Beyond the standard catalogue configurations illustrated in the shaft type reference tables shown above, CMN Transmission offers custom agricultural gearbox configurations on request for OEM customers with specific shaft diameter, length, keyway, or spline requirements not covered by the standard range.

Musim semi lalu kami membeli dua unit L-25A dari CMN Transmission untuk mengganti gearbox Comer yang sudah aus pada alat penyebar pupuk cakram ganda kami. Jujur, saya tidak bisa membedakan kualitas dan performanya. Semuanya terpasang sempurna, kualitas seal oli terlihat bagus, dan kami sudah menggunakan salah satunya sekitar 180 jam tanpa masalah sama sekali. Harganya lebih baik daripada penawaran OEM yang kami terima. Kami akan memesan lebih banyak lagi.\u201d<\/p>\n<p><strong>Thierry, Grain Farming, France<\/strong><br \/>\n\u201cSaya memesan dua gearbox L-25A untuk alat penyebar pupuk di pertanian gandum kami di Beauce. Pengiriman memakan waktu sedikit lebih lama dari yang diharapkan, tetapi layanan pelanggan sangat responsif dan terus memberi saya informasi. Setelah dipasang, gearbox bekerja dengan sempurna. Rasio 1:1,9 sesuai dengan kebutuhan kami. Saya puas dengan kualitasnya sesuai dengan harganya. Saya merekomendasikan produsen gearbox alat penyebar pupuk ini kepada petani Prancis lainnya.\u201d<\/p>\n<p><strong>Klaus, Agricultural Machinery, Germany<\/strong><br \/>\n\u201cKami mengelola bengkel mesin pertanian besar di Bavaria dan secara rutin membutuhkan gearbox pengganti untuk alat penyebar pupuk. Gearbox L-25A dari CMN Transmission identik hingga milimeter dengan suku cadang Comer asli. Keempat baut pemasangan, poros input dan output, serta rumahnya pas dengan sempurna. Saat ini kami memiliki dua belas buah dalam stok dan menjualnya kepada pelanggan pertanian kami tanpa masalah. Kualitas dan harganya tepat. Waktu pengiriman sekitar tiga minggu melalui pengiriman laut, yang dapat kami terima.\u201d<\/p>\n<p><strong>David, Orchards and Vineyards, United Kingdom<\/strong><br \/>\n\u201cSaya membeli gearbox L-25A rasio 1:1.9 untuk mengganti unit Comer yang mengalami masalah bantalan setelah sekitar 800 jam penggunaan pada alat penyebar pupuk Amazone kami. Pemasangannya sangat mudah, hanya membutuhkan waktu sekitar 45 menit termasuk pengisian oli. Gearbox ini berjalan lebih tenang daripada yang lama, bahkan saat masih baru. Satu-satunya catatan saya adalah unit ini dikirim dalam keadaan kering, jadi jangan lupa untuk mengisinya dengan oli 80W-90 sebelum digunakan! Selain itu, saya sangat puas. Nilai yang bagus dibandingkan dengan mencari pengganti Comer asli melalui jaringan dealer di Inggris.\u201d<\/p>\n<p><strong>Carlos, Sugarcane Plantations, Brazil<\/strong><br \/>\n\u201cKami membeli 6 gearbox L-25A untuk armada mesin pertanian kami di Sao Paulo. Rasio transmisi 1:1,9 sangat cocok untuk alat penyebar pupuk kami di perkebunan tebu. Kualitas aluminium dan segelnya terlihat sangat baik. Dukungan teknis CMN menjawab semua pertanyaan kami tentang level oli gearbox alat penyebar pupuk dengan sangat cepat melalui email. Pengiriman terorganisir dengan baik dengan dokumentasi lengkap untuk impor. Sangat direkomendasikan sebagai pemasok alat penyebar pupuk.\u201d<\/p>\n<p><strong>Michael, Wheat Farming, Australia<\/strong><br \/>\n\u201cKami telah menggunakan unit L-25A ini di pertanian kami di Victoria selama satu musim penuh penanaman gandum dan kanola. Kondisi di sini bisa sulit di musim panas dengan debu dan panas, tetapi gearboxnya bekerja dengan sangat baik. Tidak ada kebocoran oli, tidak ada masalah kebisingan. Kami memeriksa level oli di awal dan di tengah musim dan masih berada pada level yang tepat, yang menunjukkan bahwa segelnya berfungsi dengan baik. Pengiriman dari Korea memakan waktu sekitar tiga minggu, yang cocok bagi kami karena kami memesannya di luar musim. Pasti akan membeli lagi dari pemasok gearbox penyebar pupuk ini.\u201d<\/p>\n<p><strong>Marco, Distributor Suku Cadang Pertanian, Italia<\/strong><br \/>\n\u201cKami memesan sepuluh unit L-25A untuk pelanggan dealer kami di Emilia-Romagna. Kualitas gearbox untuk penyebar pupuk ini sangat bagus, rasio 1:1,9 telah diverifikasi dan sesuai dengan spesifikasi yang dinyatakan. Staf layanan pelanggan CMN mengirimkan gambar dimensi dan sertifikat CE kepada kami tanpa masalah. Waktu pengiriman dipatuhi. Harganya kompetitif dibandingkan dengan produk sejenis di Eropa. Pemasok suku cadang pertanian yang sangat baik.\u201d<\/p>\n<p><strong>Somchai, Nasi dan Sayuran, Thailand<\/strong><br \/>\n\u201cSaya membeli gearbox ini untuk penggantian alat penyebar pupuk pada usaha pertanian padi dan sayuran kami di Thailand. Poros input spline 1-3\/8 inci sangat pas dengan poros penggerak PTO kami dan output 25 mm terhubung ke hub cakram kami seperti yang diharapkan. Pemasangan memakan waktu sekitar satu jam dan gearbox telah beroperasi selama tiga bulan sejak itu tanpa masalah. Saya akan memberikan penilaian layanan sedikit lebih rendah karena informasi pelacakan pengiriman lambat diperbarui, tetapi kualitas produknya sendiri bagus dan kami akan memesan lagi untuk mesin kedua kami.\u201d<\/p>\n<p><strong>Robert, Manajemen Padang Rumput, Kanada<\/strong><br \/>\n\u201cSebagai importir mesin yang melayani pasar padang rumput Kanada, saya secara rutin menyediakan gearbox penyebar pupuk untuk jaringan dealer kami. CMN L-25A sekarang menjadi barang pilihan saya untuk penggantian Comer L-25A. Akurasi dimensinya konsisten baik di berbagai pesanan; dokumentasi CE selalu diberikan tanpa perlu dikejar, dan dealer saya melaporkan sangat sedikit klaim garansi. Kualitas housing aluminiumnya jauh lebih baik daripada beberapa alternatif Korea lainnya yang pernah saya coba. Logistik ke Kanada berjalan lancar. CMN adalah mitra yang andal untuk pasokan jangka panjang.\u201d<\/p>","protected":false},"excerpt":{"rendered":"<p>The L-25A Fertilizer Spreader Gearbox Ratio 1:1.9 Replacement for Comer L-25A Gearbox, also called fertilizer distributor gearbox, is an essential component of agricultural machinery, specifically designed for tasks such as soil preparation, crop treatment, and fertilizer spreading.
